2016–2021 Honda Civic Headlight and Bulb Sizes

Which Honda Civic model years does this cover?

These headlight bulbs specifications apply to every Honda Civic built from 2016 through 2021 — the 10th generation (FC/FK), compact sedan, coupe, and hatchback. Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What changed during the 2016–2021 Honda Civic

• 2016Generation launch (sedan/coupe, 2.0L and 1.5T). Two recalls hit the first year: piston pin snap rings (16V-074) and the electric parking brake software (16V-725).
• 2017Hatchback, Si (205 hp), and Type R (306 hp) join the lineup
• 2019Facelift: revised fascias, standard Honda Sensing, volume knob returns, new Sport sedan/coupe trim
• 2021Final year; sedan/hatch only (coupe dropped after 2020, no 2021 Si)

What headlight bulb does a 2016–2021 Honda Civic use?

H11 halogen (LX, EX, EX-T, EX-L, Sport, Si); full LED on Touring, hatch Sport Touring, and Type R (sealed unit) for the low beam and 9005 (HB3) halogen on halogen-headlight trims; LED on Touring/Sport Touring/Type R for the high beam. Trims with factory LED or HID projectors use a sealed assembly instead and are not bulb-serviceable.

What fog light bulb does a 2016–2021 Honda Civic take?

H11/H8 (where equipped on halogen trims).

Can you put LED bulbs in a 2016–2021 Honda Civic?

Physically, yes, LED replacements exist in every common base. Whether they work well depends on the housing: a reflector housing designed around a halogen filament scatters LED output into oncoming traffic instead of down the road. Projector housings tolerate the swap far better. Some vehicles also flag the lower current draw as a bulb-out fault.
